Answer 1

GIVEN :-

Tʜᴇ ᴘᴏᴡᴇʀ ᴏғ ᴀɴ ᴇʟᴇᴄᴛʀɪᴄ ʙᴜʟʙ ɪs 60W .

Tʜᴇ ᴇʟᴇᴄᴛʀɪᴄ ʙᴜʟʙ ɪs ᴜsᴇᴅ ғᴏʀ 6ʜrs ᴘᴇʀ ᴅᴀʏ .

TO FIND :-

Tʜᴇ ᴜɴɪᴛ ᴏғ ᴇɴᴇʀɢʏ ᴄᴏɴsᴜᴍᴇᴅ ɪɴ ᴏɴᴇ ᴅᴀʏ ʙʏ ᴛʜᴇ ʙᴜʟʙ .

SOLUTION :-

$\huge\red\star$ $\bf\purple{Energy\:=\:Power\times{Time}\:}$

ᴡʜᴇʀᴇ,

• ᴘᴏᴡᴇʀ = 60W = 60/1000 = 0.06 KW

• Tɪᴍᴇ = 6 ʜrs

• ➳ Eɴᴇʀɢʏ = 0.06 × 6

• ➳ Eɴᴇʀɢʏ = 0.36 KW.h

• ➳ Eɴᴇʀɢʏ = 0.36 units

$\huge\red\therefore$ Tʜᴇ ᴜɴɪᴛ ᴏғ ᴇɴᴇʀɢʏ ᴄᴏɴsᴜᴍᴇᴅ ɪɴ ᴏɴᴇ ᴅᴀʏ ʙʏ ᴛʜᴇ ʙᴜʟʙ ɪs "0.36 ᴜɴɪᴛs" .

Answer 2

Hey mate

Here's your answer

Given : t=6 hrs

P=0.06 kW

Thus energy consumed per day is:

E=Pt=0.06×6=0.36 kWh=0.36 units
